DC-DC 3.8V-60V (80V if 3wire) 20A Dual-display Digital LCD Power Current Voltage, AMP Meter, watt meter, Ah meter $13.69
Its little brother ... I've been using one for several months ... love it!
Many more functions but sketchy instructions are in Chinglish

New Low PriceNew Digital 60V/100A Battery Balance Voltage Power Analyzer Watt Meter - $16.07+
Auto-balancing and much more - 2s - 6s only - ordered one up!
One more reason to try a 22.2V pack for a 24V eBike!

Update - received item. Balance function works nicely, with pack voltage - no external power required.
Bleeds down higher voltage banks and beeps when balance complete.
Can even be used for bottom balancing!

I know, I know, these multimeter w/balance function have been around a long time ...
But! This model has an external power option ...
So, it will not bleed down Banks s1 - s2 during continuous operation.

Unlike a very similar previous posting, this does have continuous metering.
IR meter function seems to work ... roughly, but should be used to compare like cells. (Same brand, capacity, model, charged voltage etc. ?)
Can't vouch for discharge or balance function.

Finally I found some cheap Brush controllers ... as test items for me.
Units appear to be identical.
Thermal limits and current limit (27A +-) are identical.
Likely, units use identical components, 63V caps etc, except for LVC circuits.
Possibly, there is no HVC limit. This would allow 24V unit to run at 24-48V.
Regardless, I'm hoping to be able to identify the LVC and HVC circuit-components as simple differences between units.
I would like cheap, simple, 22.2V - 48.1V multi-battery compatibility.

it is better and cheaper to just use copper wire instead of the braided. conductivity of solid wire will be higher. if you need a flexible link the braided will work.

i just ordered another one of these cheap wattmeters because they have the calibration pots inside so i can buy a shunt at mouser and use it as the remote shunt and be able to calibrate the meter to that shunt.

also since it has no led it does not consume much power. it uses 40mA instead of the 150mA of the turnigy meter.

dnmun, Jeremy Harris wrote up how to take these cheap wattmeters and hack them into remote shunt units. Doing that you could save yourself the buying a new shunt and calibration issues by just using the existing shunt in the unit.

Are you planning your first electric bicycle conversion? I wrote a book that teaches beginners everything they need to know about building their own ebike.
Then I wrote the book (literally) on building custom lithium batteries.
I also write for EbikeSchool.com, a site that does mainly how-to style articles and other informational write-ups. Check out our youtube channel for great how-to battery building videos.
Lastly, I run www.Vruzend.com, which sells solderless 18650 battery kits, 18650 cells, li-ion chargers, BMSs and more!

I ordered 5 tiger wing 6s balancers and 2 of them broke after 2 cycles if use.

One started putting out smoke after 30mins of charging then the other turns on but the button doesn't activate the charging. The other three are fine but as a precaution now I charge at less current and obviously never unattended.

I know you get excited about all those "bargains"
Ordered 2 1-8S Lipo meters/buzzers and both are terribly unaccurate , mostly showing 1V too low ,so buzzers sound too late.
I would not relay on them at all.

I bought 3 more of these.
The last 3.
But ... "More on the way" and orders still accepted at $15.38.
The large size and nearly flat tread seem ideal for my eTrike.

UPDATED Review:
Tires are taller than previous 2.125 tires ... I had to remove fenders for good clearance.
Under pressure tread is not as flat as pictured, not recommended for heavy turning but great for more casual riding.
Tried to wear off the "whiskers" with a series of loops and swerves and observed very good turning traction.
65lb pressure, maybe aided by Kevlar belt, seems to greatly reduce rolling resistance over previous 40lb "cruising" tires of similar tread pattern.

I lucked into finding these tires that meet my requirement almost perfectly!
Tread is a a nice compromise between the mountain bike tread and the smooth tires that came with the eZip.
26" x 1.90"
Pressure @65psi is acceptably "good".
City/commuter sidewall protection. Kevlar reinforced for puncture resistance. Reflective sidewall.
The reflective stripe, though not precisely positioned (under close inspection), is a nice bonus.

- only $15.72 each.
This is great bicycle parts source w/free shipping on $100 order (USA only).UPDATED Review:
Very nice improvement over previous tires.
Center rib causes tire to track "true", there is a noticeable effort required to turn!
leaning, at higher speeds, provides very smooth turns.
Bike has excellent no handed stability without the sudden wobble experienced previously.
Good pressure, Kevlar belt and center rib combine for excellent low rolling resistance?

Just in time for Winter!

Low inventory but - Order now to insure price.

I used a similar tread pattern to build my Homemade Studded Tires, but the Kevlar belt might make "studding" these problematic?

A 12V flasher that works! ... Even with low drain LEDs!!!
Alternates between 1/16 - Full brightness approximately every .6 - .7 second.
Tested at 3 and 6 watt with no speed variance.Turn Signal Flasher Blinker Relay 12V 2 Pin Motorcycle - $1.49
Works well with either - below item single or pair.
